- Abstract
Endolithic bivalves are those species that live embedded within rocks, corals, and other substrates. In this study, the species richness, relative abundance, and diversity (H') of endolithic bivalves from the intertidal zone of Punta Maldonado, Mexico, were analyzed. The samplings were carried out in December 2016 and February 2018. For each sampling, 10 m² was covered, and in each square meter, all the bivalves embedded in the rocks were located and collected. In total, 523 specimens were analyzed, fifteen species belonging to nine families were identified, plus one specimen was identified to genus (Jouannetia). The Mytilidae family presented the highest number of species. In relative abundance, Acar rostae and Lithophaga plumula presented the highest values (30.2 % and 16.3 %, respectively). In general, the H' of the endolithic bivalves was 2.48 bits/ind. The oyster Isognomon janus and the clam A. rostae are reported for the first time as endolithic species. This is one of the first studies explorations of the diversity of endolithic bivalves from the eastern Pacific Ocean. The results of this research highlight the need to continue examining the rocky intertidal populations in order not to underestimate the current diversity of bivalve mollusks.
